Blackline Foam Cannon vs The Super Soaper – Foam Showdown

Both promise thick foam and touchless washing performance—but how does the Blackline Foam Cannon compare to The Super Soaper when it comes to results, compatibility, and real-world cleaning power?

In this post, we break down the key differences so you can choose the right tool for maximum foam and minimal scratching.

What They’re Supposed to Do

Foam cannons are designed to help you pre-soak your car with a thick layer of soap foam. This lifts dirt and lubricates the surface, reducing scratching during the wash.

But not all foam is created equal. The foam output depends on the cannon quality and the soap inside.

Blackline Foam Cannon – The Basics

• Price: ~$60
• Build: Brass internals, plastic bottle, ¼” quick connect
• Foam Quality: Good foam with correct dilution
• Included: Foam cannon only (no soap)

The Blackline Foam Cannon is a solid mid-range option with standard construction. It does what it should—but doesn’t include anything beyond the cannon itself.

The Super Soaper – Full Foam System

• Price: ~$24.99 (soap only)
• Use: Works in any foam cannon or pump sprayer
• Foam Quality: Thick, clinging foam—even with hard water
• pH Balanced: Safe for ceramic coatings, waxes, and trim

The Super Soaper isn’t a foam cannon—it’s what makes foam actually work. Paired with any foam cannon (including Blackline’s), it delivers thick, shaving-cream-style foam and safe lubrication.

Foam Performance Test

We tested both side-by-side using the same pressure washer:

• Blackline Cannon + generic soap = moderate foam, short cling time
• Generic cannon + Super Soaper = thick foam, long dwell, better cleaning
• Blackline Cannon + Super Soaper = great foam, no streaking, no harsh chemicals

Takeaway: The cannon helps—but the soap makes the foam.
